Greetings,


Just want top be safe here . Is is ok to run 12 lbs on
stock turbo without an ECU. I think not but wants some
advice.

Thanks.
Serge

 

might not be overly bad for the turbo..but you are coming close the max injector duty cycle for the stock injectors....the real issue is getting enough fuel...and avoiding fuel cut

 

12 PSI is safe for the turbos, but you need to worry about the fuel at that point. I don't think the injectors maax out until about 14 PSI. But you donm't want them maxed out in the first place.

I think fuel cut on the stock ECU is ~11.8 PSI or something arond there, depending on RPM.

 

I guess I should say not max injector duty cycle...but the max you want to see on a daily basis...12psi will easily push more then 80% duty cycle
